EDWIN HOYT, OF STAMFORD, CONNECTICUT.

TOBACCO-PIPE.

Specification forming part of Letters Patent N 0. 56,752, dated July- 31, 1866.

To all whom it may concern:

Be it known that I, EDWIN HOYT, of Stamford, in the'county of Fairfield and State of Connecticut, have invented a new and useful Improvement in Smoking Pipes; and I do hereby declare that the following is a clear and exact description thereof, reference being had to the accompanying drawings, forming a part of this specification.

Figure 1 is a longitudinal central section through the bowl of a tobacco-pipe, showing my improvements applied thereto. Fig. 2 is also a section, showing my sliding tube enlarged.

My invention consists in the arrangement of a perforated sliding tube in connection with the bore orsmoke-passage leading from the bowl of the pipe to the stem, and with a perforated diaphragm arranged across the bowl of the pipe above the said bore or smoke-passage, and with a tube leading down from the said diaphragm to an opening through the bottom of the bowl, whereby the smoke, when the pipe is in use, is drawn below the plate, so as to enter the said sliding tube through the perforations therein and pass up into the mouth; also, to provide a free passage for saliva down into a receptacle provided for it, which receptacle is the tube connected to the perforated diaphragm.

It consists, also, in arranging the perforated diaphragm above the smoke-passage, whereby a smoke-receiving chamber is formed below the diaphragm, in which the smoke can condense and precipitate its poisonous matter to the bottom of said chamber.

A designates the bowl of the pipe, B the stem, and a the bore or smoke-passage made through the side of the bowl. Across this bowl and resting on a shoulder, I), therein, or on any suitable support, there is arranged above the bore a a perforated diaphragm, C; and to the bottom of the diaphragm C there is connected a tube, D, which passes down to an opening made for it through the bottom-of the bowl, and is secured by a ball, L, or the like, which screws upon its end outside the bowl.

I will here state that I lay no claim to any of the above parts.

E is a sliding tube, one of whose ends passes into a slot or opening in the tube D, and the other, when slid forward, into the bore a. Any suitable means for sliding it back and forth (which is only necessary when it is desired to remove the perforated diaphragm and 'will be properly its appendages) may be used. In the present instance a button, 0, extending up through a slot in the diaphragm C, is provided.

It will be observed that on dropping the diaphragm C into the bowl, and guiding the tube D through the opening in the bottom thereof, and applying the ball L, the diaphragm secured. Then, by pushing the sliding tube E so that one end will enter the bore a and fit tightly therein, as shown in Fig. 2, and the other the tube D, the pipe will be ready for use.

The following may be cited as some of the beneficial results gained by this invention.

First, by reason of arranging the diaphragm C above the smoke-passage or bore a no saliva will run down from the mouth into the tobacco, as can. occur in the pipe patented to me September 26, 1865, where the diaphragm was arranged below the smoke-passage. Hence the tobacco is always dry, and will burn or smoke as well low down in the bowl as when commencing to burn at the top.

Second, the smoke is drawn down through the perforated diaphragm and into a chamber below the said diaphragm, where it has a chance to condense and deposit its nicotine and other poisonous matters on the bottom of this chamber, which chamber, therefore, also serves as a nicotine-receptacle, from which the nicotine can be removed by merely raising the tube so as to let the nicotine pass down out of the opening at the bottom of the bowl. On drawing, as in smoking, the smoke from this chamber passes into the perforated tube E through the perforations made in it, and thence up the stem to the mouth.

Third, a provision is made for clearing the stem from saliva-that is, the saliva will run down the stem (or may be accelerated by blowing in the stem) through the tube E, and down into the tube D, which, in this instance, is a saliva-receptacle.

Fourth, by this invention, while smoking,

neither the saliva nor nicotine can be sucked,

up into the month, as is evident.

What I claim as new, and desire to secure by Letters Patent, is-

The sliding perforated tube E, in combination with the perforated diaphragm C, tube D, and bore a, substantially as and for the ur oses ecified. p p p EDWIN HOYT.
